Problem
The global demand for low-carbon energy solutions is growing, yet conventional nuclear reactors face challenges related to fuel sustainability, waste management, and safety. Traditional reactors often rely on mined uranium, generating long-lived radioactive waste and raising proliferation concerns.
Solution
Newcleo is developing lead-cooled fast reactors (LFRs) and manufacturing mixed oxide (MOX) fuel to generate safe, sustainable nuclear energy while closing the fuel cycle. Their technology aims to address climate change by providing a low-carbon energy source that utilizes recycled nuclear fuel. By using LFR technology, Newcleo seeks to improve reactor safety and efficiency, while MOX fuel manufacturing enables the reuse of existing nuclear materials, reducing waste and enhancing resource utilization.
Target Audience
Newcleo's primary customers include energy providers, governments, and industrial organizations seeking advanced nuclear technology for low-carbon energy generation and waste reduction.
